Comparison of amperometric and colorimetric detection of TMB product concentrations. A range of TMB product concentrations were achieved by allowing a range of enzymatic conversion times using a single HRP enzyme concentration. Results were obtained using three different amperometric sensors, however, all colorimetric results were obtained using the same colorimetric quantification apparatus (Promega Glomax).
